- A
AWS Pricing Calculator
Why wrong: The AWS Pricing Calculator helps estimate monthly costs for AWS services based on specific configurations, but it does not include on-premises cost inputs or generate a TCO comparison report.
- B
AWS Total Cost of Ownership (TCO) Calculator
The AWS TCO Calculator is the correct tool for comparing the total cost of ownership between on-premises infrastructure and AWS. It takes on-premises configuration details and produces a report including hardware, software, labor, power, cooling, and facilities costs alongside projected AWS costs.
- C
AWS Cost Explorer
Why wrong: AWS Cost Explorer is designed to analyze historical AWS usage and costs, not to compare on-premises versus cloud TCO. It cannot incorporate on-premises cost inputs.
- D
AWS Trusted Advisor
Why wrong: AWS Trusted Advisor provides best practice recommendations across cost optimization, security, performance, and fault tolerance, but it does not generate a TCO comparison report between on-premises and AWS.
CLF-C02 Billing, Pricing, and Support Practice Question
This CLF-C02 practice question tests your understanding of billing, pricing, and support. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is evaluating a migration of its on-premises data center to AWS. The CIO wants a detailed report that compares the total cost of ownership (TCO) of the current on-premises infrastructure versus running the equivalent workloads on AWS. The report should include costs for hardware, software, labor, power, cooling, and facilities. Which AWS tool should the company use to generate this comparison?

Correct answer & explanation
AWS Total Cost of Ownership (TCO) Calculator
The AWS Total Cost of Ownership (TCO) Calculator is specifically designed to compare the costs of on-premises infrastructure with AWS, including hardware, software, labor, power, cooling, and facilities. It generates a detailed report that breaks down these cost categories, making it the correct tool for the CIO's requirement.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse the AWS Pricing Calculator (which only estimates AWS service costs) with the TCO Calculator (which includes on-premises cost inputs), leading them to choose Option A for a TCO comparison.
Detailed technical explanation
How to think about this question
The AWS TCO Calculator uses a detailed input form where you specify on-premises server configurations (e.g., CPU, RAM, storage), labor hours, electricity rates, and facility costs. It then applies AWS pricing models (e.g., Reserved Instances, Savings Plans) and generates a side-by-side comparison with charts and downloadable reports. A subtle behavior is that the calculator assumes a 3-year total cost comparison by default, which aligns with typical hardware depreciation cycles, and it factors in data center network costs like switches and cabling.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
